The recent accelerating global warming and its consequent disasters call for the immediate greenhouse gas (GHG) reduction. In this regard, the time has arrived to consider applying global warming potential (GWP) value of 20 years’ time-scale rather

Objectives To mitigate greenhouse gas (GHG) emissions, our country is trying to replace fossil fuel to hydrogen (H2). H2 has higher energy yield (122 MJ/kg) than other energy sources (natural gas, coal, etc.), and is considered a clean fuel that pro

In a lab-scale bioreactor system, (20 L of effective volume in our study) controlling a constant temperature inside bioreactor with a total volume 25 L is a simple process, whereas it is a complicated process in the actual full-scale system. There mi

Magnetite nanoparticles (MNP)-caused enhancements for H2 yield (HY) are usually justified based on oxidation-reduction potential (ORP), iron ions (Fe+2/+3) concentration, and enzymatic activity, that is pH-dependent. However, the questions “If pH,

Treatment of sulfate-rich wastewater with high methane recovery is a major concern due to sulfide inhibition. Here, an electrical voltage (EV) aims to enhance methanogenesis and sulfidogenesis to treat sulfate-rich wastewater. Two (control and EV-app
